At birth, Paul's puppy
weighed 0.375 pounds.
What is this decimal as a
fraction, in lowest terms?
Answer:
3/8
Step-by-step explanation:
since 0.375 has three digits after the decimal, it's in the thousandths place.
use the equation (0.375 x 1000) / 1000 to get the fraction 375 / 1000
since it's not in simplified form, you'll need to divide both the numerator and denominator by the highest common factor (the highest possible number which divides both the numbers exactly; via cuemath.com), 125.
use the equation (375 / 125) / (1000 / 125) to get your final answer
375 divided by 125= 3
1000 divided by 125= 8
ans.- 3/8
I’m not very good at math and I need help
The answer would be 6.00%
Answer:
C
Step-by-step explanation:
First of all it's not that you aren't very good at math it's just that you don't YET understand the concepts,... Believe me when I say that I've been there!!!
To solve this problem you have to look at it as a solve for the unknown problem,... They say that The FORMULA (important) is the following:
S = Ar
This can be written:
S = A * r
They then say that
S = sales tax,
A = cost of the product
r = local sales-tax rate,...
THEN they start giving you information,... they say the COST of a television (cost of the product) is $400 dollars you can now enter this info in you formula,... A = cost of product,... so switch the letter with the assigned info,...
S = $400 * r
...and the sales tax is $24 dollars,... S stands for sales tax so switch the variable for the dollar amount,...
$24 = $400 * r
Now you just have to solve the equation (figure out $400 * what = $24) and easy way to do this is to simply divide $24 by $400,...
$24/$400=0.06,...
0.06 = 6.0% = 6.00%
Hope I helped, You can learn anything!,... Me out,... Chow,...!

Answer:

Step-by-step explanation:
The perimeter is the sum of the 3 sides of the triangle , that is
3x + 2x + 6 + 6x - 3 ( simplify by collecting like terms )
= 11x + 3
Given the perimeter = 36 units , then
11x + 3 = 36 ( subtract 3 from both sides )
11x = 33 ( divide both sides by 11 )
x = 3
Then
base = 2x + 6 = 2(3) + 6 = 6 + 6 = 12 units
height = 3x = 3(3) = 9 units
hypotenuse = 6x - 3 = 6(3) - 3 = 18 - 3 = 15 units

Rewrite the equation in slope-intercept form. Then identify the slope and the y intercept of the line
4x + y = 1
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
4x + y = 1 ( subtract 4x from both sides )
y = - 4x + 1 ← in slope- intercept form
with slope m = - 4 and y- intercept c = 1
Explain what the vertical line test is and how it is used.
Answer:
The vertical line test is a way to figure out if a figure on a graph is a function. Imagine a vertical line goes across the graph from left to right. If the line touches two points at the same time, it's not a function.
Answer:
Sample Response: The vertical line test is a way to determine if a relation is a function. This test determines if one input has exactly one output on the graph. If any vertical line passes through more than one point on the graph, then the relation is not a function because two different outputs have the same input.

if you make $391 for 17 hours how much would you make in 13 hours
Answer:
We would make $299 in 13 hours.
Step-by-step explanation:
Hi there!
We're given:
⇒ We make $391 in 17 hours
To find how much we make in 13 hours, we must first find how much we make in 1 hour. Divide $391 by 17 hours:
391 ÷ 17 = 23
Therefore, we make $23 in 1 hour.
Multiply $23 by 13 hours to find how much we would make in 13 hours:
23 × 13 = 299
Therefore, we would make $299 in 13 hours.

Answer options with 5 options
A. 1
B. 5
C. 7
D. 8
E. 16
Answer:
E. 16
Step-by-step explanation:
How I solved this is I used a ratio. 1:4 (Meaning 1 penny from Sam is 4 from Tara ). So if Sam has 4, you have to multiply 4 by 4 to. So 4:16. I hope that makes sense, if it doesn't I can explain

9. A teacher places seven cards, lettered A-G, on
a table. Which cards show irrational
numbers?
Answer:
Cards C and E
Step-by-step explanation:
Remember that irrational numbers cannot be written as a fraction of two integers:
Is 10 irrational? No, because 10 can be written as a fraction (ex. 10/1, 20/2, etc.)
Is 6/5 irrational? No, because it is a fraction.
Is π irrational? Yes, because it can't be written as a fraction as its digits continue infinitely without repetition.
Is 11/4 irrational? No, because it is a fraction.
Is 8.25635... irrational? Yes, because the ellipsis shows the digits continue infinitely without repetition, otherwise there would be a bar over the digits to show repetition
Is -7 irrational? No, because it can be written as a fraction (ex. -7/1, -14/2, etc.)
Is 6.31(bar) irrational? No, because the bar shows that the digits 3 and 1 repeat.
Therefore, only cards C and E are irrational.
The cards that represent irrational numbers are C (π) and possibly E (8.25635), as π is a well-known irrational number and E is a decimal with multiple digits. The other options represent rational numbers.\
The cards that show irrational numbers are:
C. π (pi) - π is an irrational number representing the ratio of a circle's circumference to its diameter.
E. 8.25635 - This number is not known to be irrational based on the given information, but as it is a decimal with multiple digits, it could potentially be irrational.
The other options, A, B, D, F, and G, represent rational numbers, either whole numbers or fractions, and are not considered irrational.

Given sides of the triangle:
3x^2 + 8,2x^2 + x, andx - 3.We know that the perimeter of a triangle is the sum of all the sides of a triangle.
Perimeter of the triangle,
= 3x^2 + 8 + 2x^2 + x + x - 3
= 3x^2 + 2x^2 + x + x + 8 - 3
= 5x^2 + 2x + 5
Therefore, the perimeter of the triangle is 5x^2 + 2x + 5. Hence, the option A is the correct answer.
